Another good category theory read is Pierce's Category Theory for Computer Scientists

What practical applications does it present for programmers? I've looked at this a bit and it just seems like a regular category theory book.

Sometimes it is helpful to really understand what the hell you are actually doing when you write code (design patterns, data types and all). Otherwise, not much (unless you write Haskell, that is.)

You don't get scared when you read stuff about Haskell because you know what most the fancy words mean

On the other hand it would be easier to just avoid Haskell.
